IMPROVEMENT IN LAMP-BRACKETS.

Specification forming part of Letters Patent N o. 190,271, dated May 1,1877; application filed March 31, 1877.

To all whom it may concern:

. Be it known that we, OHAs. BLWEN and GEO. D. PARKER, of Norfolk, in the county of Norfolk and State of Virginia, have invented a new and valuable Improvement in Lamp Attachments; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification. and to the letters and figures of reference marked thereon. I

Figure 1 of the drawings is a representation of a side elevation of our lamp attachment as applied, and Fig. 2.. is a central vertical sectional view thereof when closed. Fig. 3is a detail view of the same.

The object of this invention is to provide an illuminating attachment for sewing-machines which can be readily adjusted, so as to throw its light only upon the needle and its immediate surroundings.

In the accompanying drawings, A designates the topof the sewing-machine table or support, which serves also as the top of a depending box or casing, B, having a door or cover, b. To said table-top, A is attached a longitudinally-slotted plate, G, that holds a metal block, D. Said block is provided with clamping-nut E,working on bolt F, that extends from said block.

H designates a third constructed wholly of metal.

slotted plate or bar, which is clamped by nut I and bolt'I to plate G, and provided atthe top with an annular lamp-holder, J, which supports lamp'K. The chimney L of said lamp is of metal, and has but a single opening, L, for the emission ot' light. M desighates an eye-shade, pivoted, by means of bent rod or rods M, to a socket, m, on the side of said chimney. Said chimney is preferably provided with a reflector opposite to opening L. and maybe made of glass. covered by a metallic sleeve, but is more durable when By means of the slotted plates 0 GE, block D, and the clamping bolts and nuts hereinbefore described, the said lamp can be raised above the top of the table, and arranged to cast a beam of light, through opening L, directly upon the needle of the sewing-machine, and upon its immediate surroundings, Without lighting the remainder of the machine or daz zliug the eyes of the operator. It can also be folded within box B, as shown in Fig. 2.

When not needed the door orcover b is closed to protect it more elfectually. A gas-burner having a flexible connection may be substituted for said'lamp.

What We claim as new, anddesire to secure by Letters Patent, is-

The combination of slotted plates or bars 0 Gr H, casing. B, block D, lamp-support J, and clamping screws and bolts, substantially as and for the purpose set forth.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
